Footpath d1, the d2 of wire and size and the number of plies of mesh m1, m2, can suitably set according to the flow of refrigerant.
Discoid the 1st porous part 11 is relative to the configuration and is communicated with inflow side passage 22 by intercommunicating pore 94.The described discoid side of described the 1st porous part 11 and the 24 subtend configurations of described intercommunicating pore.
Described the 1st wire netting 11A of described the 1st porous part 11 is configured in the upstream side that refrigerant flows into from described intercommunicating pore 94, and described the 2nd wire netting 11B1 and 11B2 are arranged on its downstream side.
Described throttle orifice parts 12 are by the metal formed disc-shaped structure of brass material for example, described throttling path 12a relative with described the 2nd wire netting 11B1 and 11B2 to and configure.
Described the 2nd porous part 13 is by the wire in prescribed level footpath stainless steel material for example, by irregular, is entwined, or combined the forming of wire netting being formed by the irregular wire netting being entwined and rule braiding.Described the 2nd porous part 13 forms density mesh by described wire and forms, and it is discoid that the 2nd porous part is set to be connected with described throttle part 12.
Described valve rod 9 in described space 93e successively with described the 1st porous part 11, described throttle part 12 and the tight chimeric configuration of the 2nd porous part 13.Utilize the tip portion 93d1 of the described protuberance 93c of described valve rod 9, surrounding's enforcement riveted joint to described the 2nd porous part 13 is fixing, and makes described the 1st porous part 11, described throttle part 12 and the 2nd porous part 13 insert fixed configurations on valve rod 9.By it, fix, make access 94, described the 1st porous part 11 and described throttle part 12 (being described throttling path 12a) and described the 2nd porous part 13 form the coolant path of valve rod 9.
Next the action of solenoid valve 1 in the 1st mode of execution is described.
When electromagnetic coil 3 is by lead-in wire 32 during the state in energising, according to the energising of electromagnetic coil 3, produce the magnetic force of opposing compression helical spring 8 spring forces, thereby attractor 10 attracts core iron 6 downward directions, core iron 6 is in the interior movement of sleeve part 4, and then valve rod 9 is attracted son 10 guiding and moves to seat portion 27.Be that valve rod 9 moves to closing valve direction, the periphery valve face 93d of the 93b of wall portion of the valve portion 93 of valve rod 9 and the internal face close contact of seat portion 27, thereby make valve rod 9 seat in seat portion 27.As shown in Figure 4, solenoid valve 1 is for closing valve state for result, valve rod 9 and the 1st porous part 11 relative with inflow side passage 22 to and configure, thereby can close valve by solenoid valve 1, operate.
The valve state that closes as shown in Figure 4, the outflow side passage 23 of the inflow side passage 22 of import side pipe 25 and outlet side pipe 26, is communicated with by the 1st porous part 11 and intercommunicating pore 94 and throttling path 12a and the 2nd porous part 13.
When freeze cycle is when dehumidifying is turned round, refrigerant flows into from import side pipe 25, then by intercommunicating pore 94, flow into the 1st porous part 11, because the size of the 1st porous part 11 mesh is regularity and the multi-ply constructions uniformly that consist of sintered meshwork, so the refrigerant flowing into is slowed down, the flowing state of the gas-liquid 2 phase refrigerants in refrigerant also forms and homogenizes, therefore, can be simple and definite make the bubble sectionalization in refrigerant.Because the 1st porous part 11 is by multi-ply construction, in the mobile direction of refrigerant, be provided with certain thickness, so can carry out for a long time bubble sectionalization.Moreover, multi-ply construction is owing to being that large footpath (d1) wire forms the Construction integration that the 1st wire netting 11A of few mesh amount (m1) and the 2nd wire netting (11B1 and 11B2) that path (d2) wire (d1 > d2) forms many mesh amount (m2) (m1 < m2) form by sintering, so the 1st wire netting 11A is as the framework layer of described the 1st porous part 11, when refrigerant flows into, can be when guaranteeing the 1st porous part 11 intensity, due to the upstream side of the 1st metal mesh arrangement in refrigerant inflow, so the 1st wire netting 11A can make the 1st porous part 11 be difficult for producing distortion and crooked, therefore, can realize a kind of long lifetime the 1st porous part that can reduce refrigerant flow noise.Form the 2nd wire netting 11B1 and 11B2 of multi-ply construction together with the 1st wire netting 11A, owing to being formed by mesh m2, so as the dispersion layer of the 1st porous part 11, can realize for a long time the stingy alveolation of bubble in the refrigerant after sectionalization.
In addition, the 1st wire netting 11A and described the 2nd wire netting 11B1 and 11B2 are stainless steel sintered meshwork, so, can realize heat-resisting quantity and the resistance to deformability of the 1st porous part of described multi-ply construction.As a result, can realize and a kind ofly can reduce refrigerant flow noise, and then suppress the solenoid valve of noise producing.In addition, the described porous part 11 of the 1st wire netting 11A and described the 2nd wire netting 11B1 and the formed described multi-ply construction of 11B2, by punch process, form discoid, because this discoid the 1st porous part is configured in the described space 93e in the 93b of wall portion of described valve rod 9, so can realize a kind of noise reduction the 1st porous part 11 with high manufacturing accuracy and high work efficiency, thereby, this noise reduction porous part, not only production is good, low-cost, but also can be definite make bubble sectionalization.As a result, there is the solenoid valve 1 of described the 1st porous part 11, also can realize low cost, long lifetime and reduce refrigerant flow noise.
Even if flow into the gas-liquid 2 phase refrigerants that exist in the refrigerant of the 1st porous part 11, there is pressure pulsation, owing to can obtaining by described multi-ply construction the refrigerant that pressure pulsation homogenizes, so flow into the refrigerant of throttling path 12a, form successional pressure pulsation, therefore, by throttling path 12a, can stablize and effectively carry out throttling, thereby can reduce refrigerant flow noise.
In addition, even can grow up in mobile process in throttling path 12a by the bubble in the refrigerant after the 1st porous part 11 sectionalizations, become large or can grow up after by throttling path 12a and become greatly, but while growing up bubble inflow the 2nd porous part 13 that becomes large in refrigerant, by the 2nd porous part, can make it become large bubble sectionalization.The wire that is stainless steel material due to the 2nd porous part 13 forms the different wire netting of mesh density by irregular braiding, therefore, flow in the refrigerant of the 2nd porous part 13 and grow up and become large bubble, sectionalization that can be definite by described mesh, thereby the refrigerant flow noise in the time of can reducing by the 2nd porous part, result makes refrigerant flow to outflow side passage 23, and interior mobile at outflow side pipe 26.
By the 1st porous part 11 and throttling path 12a, can make to be inhibited because of the pressure pulsation that refrigerant flow rate change produces, thereby can reduce pressure oscillation.As a result, due to refrigerant can homogeneous 2 circulation circulation flow path 12a that celebrate a festival mutually, so can realize a kind of pressure oscillation, can be inhibited, and be difficult for producing noise, and can obtain a kind of solenoid valve of stablizing coolant throttle effect.
And, after coolant throttle effect, even if refrigerant flows out from throttling path 12a, bubble occurs to grow up while becoming large, because refrigerant flows to the 2nd porous part 13, so when refrigerant passes through the 2nd porous part 13, bubble in refrigerant is segmented, thereby can reduce the flow noise of refrigerant.Therefore, can realize a kind of solenoid valve 1 that can stablize dehumidifying operation under the prerequisite that reduces refrigerant flow noise.
In addition, as mentioned above, the metal net structure with density mesh that the 2nd porous part 13 forms for irregular braided metal line, but the present invention is not limited to this structure, also can be regular braided metal line and the meshed wire netting of tool that forms and above-mentioned irregular braided metal line and the structure with density mesh that the wire netting with density mesh that forms combines.From the 2nd porous part 13, bubble in the refrigerant that throttling path 12a flows out occurs to grow up while becoming large, because the 2nd porous part can be the combination of the meshed wire netting of the formed tool of irregular braided metal line and the meshed wire netting of the formed tool of regular braided metal line, so, by this combination, can make the mesh of the 2nd porous part be set to have the structure of density, therefore the growth in refrigerant that makes that, can be definite by the 2nd porous part becomes large bubble sectionalization.Therefore, can realize and a kind ofly simply can reduce refrigerant flow noise, and further suppress the solenoid valve 1 of noise producing.
To sum up, the solenoid valve 1 in the present invention's the 1st mode of execution, when long-term use, not only can reduce the flow noise of refrigerant, but also can realize can be certain carrying out stablize the exsiccation of throttling.
When the electric current to lead-in wire 32 is disconnected, because attractor 10 does not produce magnetic force, attractor 10 loses the attraction force to core iron 6, so the core iron 6 in sleeve part 4 is the urging force of compression helical spring 8 according to the spring force of compression helical spring 8, to the reciprocal top of attractor 10, moves.Thereby valve rod 9 is in the inside guiding of attractor 10 cylindraceous and be moved upward together with core iron 6, as shown in Figure 1, the lift off a seat internal face of portion 27 of the valve portion 93 of valve rod 9.As a result, outflow side passage 23 is opening state, and refrigerant passes through, after seat portion 27, through outflow side passage 23, to flow to and flow out side pipe 26 through inflow side passage 22 from flowing into side pipe 25, thereby valve operation left by solenoid valve 1, forms the valve state of opening without throttling action.This is opened under valve state, as shown in Figure 1, valve rod 9 is not to be arranged in valve chamber 21 refrigerants from the stream of inflow side passage 22 inflows, therefore, refrigerant can not flow into the 1st porous part 11, the throttling path 12a being positioned on valve rod 9, and in the formed coolant path of porous part 13.
In the invention described above embodiment's explanation, as shown in Figure 2, in the inner space 93e of described valve rod 9, dispose described the 1st wire netting 11A of multi-ply construction and discoid described the 1st porous part 11 that described the 2nd wire netting 11B forms, in when configuration, by the described intercommunicating pore 94 of the described discoid side of described the 1st porous part 11 and described valve rod 9 relative to and configure.
In addition, described the 1st wire netting 11A that forms described the 1st porous part 11 is configured in refrigerant and by described inflow side passage 22, is flowed to the upstream side of described intercommunicating pore 94, for above-mentioned refrigerant, by described the 1st wire netting 11A, the situation of the bubble sectionalization in its refrigerant is described, but the present invention is not limited to this kind of situation, and, when the refrigerant from described intercommunicating pore 94 is during by described the 1st porous part 11 sectionalization, above also can making its refrigerant import to that described the 1st wire netting 11A is relative with described the 2nd wire netting 11B to toss about below butt.
Fig. 5 is the structural representation of the valve rod of another embodiment of the present invention; Fig. 6 is the structural representation of the throttle part in Fig. 5.
In another embodiment of the present invention, the embodiment of the valve rod 9 ' of of the present invention critical piece identical with Fig. 2 described in above-mentioned situation as shown in Figure 5.In Fig. 5, the all-round circle shape groove 93f being connected with described intercommunicating pore 94 that is formed with in inside, described groove 93f and described the 1st porous part inside that is formed on described valve rod in opposite directions of the described par 93a that forms are connected with the described wall 93b of portion of described valve rod 9 '.Further, described groove 93f and above described the 1st wire netting 11A the shoulder 11A1 of 11A2 arrange in opposite directions.And, described shoulder 11A1 arranges by rake 11A4, described rake 11A4 forms as the described discoid circle edge of 11A2 above, the reverse side of described 11A2 to be above described the 1st wire netting 11A relative with described the 2nd wire netting 11B of the described multi-ply construction of formation below butt 11A3.Described rake 11A4 arranges to the side that is provided with the described wall 93B of portion of described intercommunicating pore 94 as plane of inclination 11A2 above described, and meanwhile, described rake 11A4 is arranged on described circle edge all-round of the described 11A2 above of described the 1st wire netting 11A.Therefore, the described circle shape groove 93f of described shoulder 11A1 and described valve rod 9 in opposite directions be arranged on the all-round of described the 1st wire netting 11A.
